Products Details

Power station valve, also known as power station special valve, is mainly used in the pipeline of various systems of thermal power station, used to cut off or connect the pipeline medium. The power station valve is characterized by being able to withstand high temperature and pressure, and has a unique self-sealing design, making the higher the pressure, the more reliable the sealing. This valve is suitable for water, steam and other non-corrosive media.

There are many kinds of power station valves, including electric gate valve, check valve, extraction check valve, instrument valve, process valve, trap valve and power station butterfly valve. They are widely used in the four major pipelines and extraction steam systems, high pressure bypass inlet and high pressure water supply pipelines, main steam systems, desulfurization and denitrification systems and other key parts of power plants.

The design and manufacture of power station valves follow a series of standards, such as GB/T12234, ASMEB16.34, JB/T3595, etc. These standards cover the design and manufacture, structural length, interface connection size, inspection and testing, pressure and temperature reference.

The structural advantages of the power station valve include the use of pressure self-tightening seal, the valve body branch pipe is welded at both ends, the valve seat and disc sealing surface is made of wear-resistant material plasma spray welding, and the valve stem is specially treated to have good corrosion resistance and abrasion resistance.

With the development of technology, the design of power station valves is also constantly innovative, such as the use of new materials and structures to adapt to higher working parameters and more stringent industrial requirements. For example, Nantong Power Station Valve Co., Ltd. since its establishment in 1960, focusing on the development and manufacture of various high, medium and low voltage power station valves, its products are widely used in nuclear power, thermal power, petrochemical, steel, environmental protection and other industries, and exported to Southeast Asia and other regions.

The selection and application of power plant valves need to consider their performance and technical requirements under specific working conditions to ensure the safety and efficiency of the power plant.
